Line Data

History

The line started out with the section between Shin-Sakuradai and
Kotake-Mukaihara, and began through operations with The Eidan
Subway Yūrakuchō Line (Now Tokyo Metro). At this
point, the line did not connect with any other Seibu Line, thus
making it so that only Eidan trainsets were used. In 1994, the
sector between Shin-Sakuradai and Nerima opened, connecting with
the Seibu Ikebukuro Line. Because of
track elevation work at Nerima, only one track was used. Later in
1998, the sector between Shin-Sakuradai and Nerima became 2 tracks,
and also began through service with the Ikebukuro Line.
